Michael Jantzen's Amazing 1981 Modular Steel Dome House

"In this design, I merged four 26-foot diameter outer domes together (on a concrete slab floor) in a soap bubble fashion, with four more 24-foot diameter domes merged on the inside, leaving one foot of space between the two clusters of domes.

"This space was then filled with cellulose insulation. I developed custom doors and windows, with special shade louvers mounted over the windows to control the amount of solar heat and light entering the structure."
